In the unit, you found the probability of a compound event by identifying the sample space. However, it is also possible to find the probability of a compound event without finding the sample space. To do this, multiply the probability of the first event by the probability of the second event. For example, the probability of flipping heads twice on a coin is . Using this idea,1/2 x 1/2 =1/4 what is the probability that the next cougar and bear caught will both be unmarked?

Answer:

13/25

Step-by-step explanation:

Probability cougar will be unmarked :

⇒ Number of unmarked cougars / Total cougars

⇒ 865 - 173 / 865

⇒ 692/865

4/5

============================================================

Probability bear will be unmarked :

⇒ Number of unmarked bears / Total bears

⇒ 1,940 - 679 / 1,940

⇒ 1,261/1,940

13/20

===========================================================

Probability both will be unmarked :

⇒ 4/5 × 13/20

⇒ 52/100

13/25
